Where are you hearing the exit poll matched the outcome? I've seen two separate reports which say the exit poll (leaving the voting booth) had Obama winning Hampshire.

As for fraud...Sure in 3rd world, communist and developing nations I can see exit polling as a tool for uncovering fraud. As for me not being counted...I'm sure there are many like me who remain quiet about our vote. There is a reason for the private booth...I'm not in Iowa where I stand in a group under a sign.
